It isn't a pleasant thought. Sinners were/are the authors and the ministers of all the sufferings that the divine Redeemer endured. We can say it that way or we can say we killed Christ. Either way the logic is sound.I have indeed, along with the footnotes! Christ never taught that we killed him with our sins. On the other hand, one of the footnotes does reference Jesus saying that whatever we do to the least ones, we do to him. Nor do I doubt our sins today cause him pain, our indifference to others sickens him.Have you read the catechism on this?
